Two more people have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for medical care and have since been discharged.
Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of a number of individuals injured by a noxious substance thought to be pepper spray.
The attack - which police said was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
